    So I notice in my "My Verizon" app, it shows my line's data usage of over .500 gb. Not a whole lot, but 2 days before it was at .120 gb. I went online to get a better look. It showed a usage of .406 gb at 2:21 pm on the 10th. I do very little off wifi. So when I called Verizon about my plan, I asked about it. Of course they can't see what you do, but she said it occurred during a 6 hour window between 2 pm and 8. The only thing I did off wifi, was go outside and check my LTE speeds on my speedtest.net app. I may have checked 3 locations. That was all I did off wifi. Could that have used .406 gb of data?
    Also, she said if I open an app on Cellular, then go home where I auto connect back to wifi, the app continues to run on Cellular unless I force close it. I never heard that before. The person that told me that was a tech support specialist. True or false?

    I think it's probable that you used up that amount of data through the app since you ran it three times. As for the cellular to Wi-Fi connection, you opened the app using cellular data... making the switch to Wi-Fi should change over unless the app is set to use Cellular Data. Force closing the app and reopening it would switch the data connection to Wi-Fi.

    So you're saying checking speeds using the speedtest.net app one time on LTE uses about .130 gb of data? That seems like a lot for something that takes about 20 or 30 seconds.

    It does seem like a lot but I'm not sure how that data is measured.

    Speedtests don't use that much data. Each LTE test should use around 10 Mb. I think the problem is that the usage statistics don't reflect the actual date. It may have been usage from a day or two before that hadn't caught up yet. You also might have stuff running in the background.

    I'm gonna reset the data counter to 0 in settings, then turn wifi off and do another speedtest.net test and then check Settings. Today's our last day in the billing cycle with about .900 gb left. If I run it over, I'll blame my son and make him pay the overage. LOL. I am curious how much the speed test uses.

    I updated iOS 8.1.2 early that morning, but was on wifi. The tech confirmed the usage took place between 2 pm and 8. A 6 hour window. I hate not knowing what caused it. I've had a couple of spikes before, with no idea what it was. One was .156 gb at 1:30 am and one was .234 gb at 7:30 am. Those were a year ago. Nothing like that again until Wednesday.

    I've continued to experience wifi weirdness especially first thing in the morning when I might want to stream the news. It could be that those late night data spikes coincide with iCloud syncs when wifi is down for whatever reason(s).
    Just spitballing ...
    YMMV

    I normally go to bed with a full charge. But I have done overnight charging. I restarted my data counter in settings yesterday. It's the first day of my Verizon billing cycle. I've used 608 KB of data in 1 day while on wifi. :rolleyes:

    What about background apps that might be using data in the late hours? I'd check as well background refresh ssettings. Or force closing apps that you know use days until you need them open.

    Nah! None of that would produce a usage of .406 gb. It was between 2 pm and 8 pm. It hasn't happened again.
